Loose-Lear BINDER.

Application filed October 12; 1923- Serial No. 668,096.

spects hereinafter appearing; and-more particularly, to provide such a device having improved means for locking the leaf-binding members thereof in. position; ant. turtherfto provide such members has-ring improved features of construction.

These and any other objects hereinafter appearing are attained by, and the invention finds preferable embodimentin, the structure hereinatter particularly cescribed in the body of this specification and illustrated by the accompanying drawings, in which Figure 1 is a longitudinal sectional view of a loose-leaf binder taken on line l l of Figure 2;

Figure 2 is a top plan view of the same, partially sectioned on line 22 of Figure 1;

Figure 3 is a detail view of part thereof, but showing the post-engaging catches or the device in another position;

Figure l is a detail view showing in outeredgewise position one of said catches and the slidable bar on which it is mounted;

Figure 5 is a transverse sectional View of said catch and bar taken on line 5-5 of Figure 4:; and

Figure 6 is a View similar to Figure 3, but showing said catches disengaged from the post.

In the construction illustrated by the drawings, the loose-leaf binder has a pair of cooperating leaf-binding members 1, 2, between which the contents of the binder the loose leaves 3--are held. ing posts 4-. are carried by the under member 2, extending through and secured in registering openings 5, 6, in the spaced opposite sides 8, 9 of a portion 10 of said member and in the opening 7 in the body portion 11 of said lower member, these threeopenings being in registration with each other. These posts pass through openings 12 adjacent the binding edge of the loose leaves 3. The upper portions of these posts are pro vided with recesses, preferably the annular grooves 13 shown in Figure 1. The upper leaf-binding member 1 comprises a body portion 14 and a second portion 30 having spaced opposite sides 15, 16, openings 17, 1. 19 registering with each other extending through said opposite sides and said body member. The recessed ends of the posts 4 are receivable removably into these openings.

A pair of bincb lidably bearing between the opposite sides 10. 16 or the upper leaf-binding member 1. a bar 20 carries two pairs (only one pair however being shown) of catches 21, each catches straddle and holdingly engage yield ingly in rer 13 on the opposite sides of the post. ii hen the bar 20 is slid outwardly by drawing i" handle portion 29, the catches moved out oi contact with the posts and the upper leaf-binding member 1 may be re moved, whereupon lerves may be inserted into the binder or removed therefrom.

Inasmuch as the portions ant 10 are secured as by rivets, spot-welding or, otherwise to the body portions 14:, 11 respectively of the upper and lower leaf-binding memhere, it will be seen that the posts 1 are held securely on the lower member 2 and 'uided against any considerable tilting movement in the openings in the upper member 1.

The upper and lower leaf-binding members 1, 2 have respectively the right-angle extensions or plates 31, 82 extending toward and overlapping each other, thus forming a heel: for the binder and its contents, and each leaf-binding member has a swingable cover 33 or 34 pivotally connected therewith.

by the pintle hinges 35, 36.

The invent-ion being intended to be pointed out inthe claims, is not to be limited to by details oi construction of the particir lar embodiment thereof illustrated by the drawings or hereinberore shown or described.

I claim:

1. In a device of the character described: a leaf-binding member having a post provided with lateral recesses; a second leafbinding member; a bar slidably bearing in the last-mentioned member and carrying a pivotally-mounted catch spring-pressed toward the post and movable by the sliding of the bar to a position wherein it holdingly engages yieldingly in a recess in the post and to another position wherein it disengage's the same.

2. In a device or the character described: a leaf-binding member having a post pro vided with lateral recesses; a second leatbinding member; a bar slid-ably bearing in the last-mentioned member and carrying a pivotally-mounted catch spring-pressed to ward the post andhaving aned-ge, aportion of which is convex toward the post and an other portion nearer the catchs pivotalmonnting which is roncave toward the post, the catch being movable by thesliding of the bar to a position wherein said concave portion holdingly engages yieldi'ngly in a recess in the post and to another position wherein the catch disengages the same.

3; In a device of the character described: a leai binding membenharing a post provided with lateral recesses; a second leafbinding'rmeniber; a bar slidably bearing in the last-'mentione d member and carrying a pair of separately pi'votally-mounted catches spring-pressed toward the post and movable by the sliding of the bar into a position wherein they respectively holdingly engage yieldingly in recesses in the opposite sides of the post and to another position wherein they disengage the same.

4. In adevice of the character described: a leaf-binding member having a post provided with lateral recesses; a second leafbinding member comprising a body portion and a portion secured thereto having spaced oppositesides; a bar slidably bearing between said opposite sides and carrying a pivot ally-inonnted catch spring-pressed toward the post and movable by the sliding of the harm a position wherein it holdin'gly engages yieldingly in a recess in the post, and another position wherein it disengages the saine.

In testimon' whereof I have hereunto set J a my hand at Grand Rapids, B'Iichigan, this 8th day of October, 1923.
